Effective referral management of health and clinical services in maternal and child health hospitals plays an important role in enhancing patients′ medical experience, improving the efficiency and quality of maternal and child health services. A tertiary grade A maternal and child health hospital has carried out a practice of health and clinical service referral management based on information technology construction. A referral information module embedded in the hospital information system has been designed and constructed, and started to be applied in outpatient clinics in July 2021. At the same time, corresponding system and process construction, as well as quality control management and continuous improvement, have been carried out. The outpatient referral rate from July to December 2021 was 2.8% (11 466/412 808), from January to June 2022 it was 5.6% (22 705/402 586), from July to December 2022 it was 5.5% (22 233/402 959), and from January to June 2023 it was 6.7% (23 373/347 898). The referral rate has continued to improve and can provide reference for the referral management of other maternal and child health institutions.

Objective:To investigate the effect of methylene blue (MB) on motor dysfunction and its mechanism in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease (PD) mouse models.Methods:Forty healthy male C57BL/6 mice were randomly divided into 4 groups: control group, model group, low-dose treatment group and medium-dose treatment group ( n=10); PD mouse models were established by intraperitoneal injection of 25 mg/kg/d MPTP for a consecutive 7 d; low-dose treatment group and medium-dose treatment group were pretreated intraperitoneally with MB 2 mg/kg/d or MB 10 mg/kg/d for a consecutive 3 d, respectively; and then, MPTP 25 mg/kg/d+MB 2 mg/kg/d or MPTP 25 mg/kg/d+MB 10 mg/kg/d were injected intraperitoneally into the low-dose treatment group or medium-dose treatment group for a consecutive 7 d (MPTP and MB were given at 12 h of interval). Eight d after modeling, open field experiment, pole climbing experiment and rod rotating experiment were carried out to evaluate the spontaneous movement, coordination, endurance and motor ability. And then, the mice were sacrificed; immunofluorescent staining was used to observe tyrosine hydroxylase (TH) expression in the substantia nigra; Western blotting was used to detect the expressions of TH, α-synuclein, nucleotide-binding oligomerization domain, leucine-rich repeat and pyrin domain-containing 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), cleaved-Caspase-1 and Gasdermin D (GSDMD) in the striatum and substantia nigra of mice. Contents of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-18 in the substantia nigra and striatum of mice were detected by ELISA. Results:Compared with the control group, the model group had shortened residence time in rod rotating, prolonged descent time in rod climbing, reduced total movement distance in open field, decreased number of TH-positive cells in the substania nigra, decreased TH protein levels in the substania nigra and striatum, and increased NLRP3, ASC, cleaved-Caspase-1, GSDMD and GSDMD-N protein levels in the substania nigra and striatum, and increased TNF-α, IL-1β and IL-18 contents in the substania nigra and striatum, with significant differences ( P<0.05). Compared with the model group, low-dose treatment group and medium-dose treatment group had prolonged residence time in rod rotating, shortened descent time in rod climbing, increased total movement distance in open field, increased number of TH-positive cells in the substania nigra, and increased TH protein levels in the substania nigra and striatum, decreased NLRP3, ASC, and cleaved-Caspase-1 levels in the substania nigra and striatum, and decreased TNF-α, IL-1β and IL-18 contents in the substania nigra and striatum, with significant differences ( P<0.05). No statistical differences in the above indexes were noted between the low-dose treatment group and medium-dose treatment group ( P>0.05). Conclusion:Low-/medium-dose MB can ameliorate motor dysfunction in PD mouse models, whose mechanism may be related to downregulate NLRP3 inflammasome and inhibit neuroinflammatory response to reduce dopaminergic neuron pyroptosis.

Objective:To explore the relationship between the expressions of P21,P27 and proliferating cell nuclear antigen(PCNA)in glomerular mesangial tissue and poor renal prognosis in patients with immunoglobulin A(IgA)nephropathy.Methods:A total of 145 patients with IgA nephropathy treated in Xiaogan Central Hospital from April 2017 to August 2019 were selected as the research object.The expressions of P21,P27 and PCNA in glomerular mesangial tissue were detected by immunohistochemistry.All patients were followed up for 24 months,and the prognosis were counted.The expressions of P21,P27 and PCNA in glomerular mesangial tissue of patients with different prognosis were compared and the influencing factors of poor prognosis in patients with IgA nephropathy were analyzed by Logistic regression analysis.Results:The expression rates of P21,P27 and PCNA positive cells in glomerular mesangial tissue of patients with IgA nephropathy were(38.69±6.83)%,(55.94±8.08)%,(33.47±5.72)%,respectively.The incidence rete of poor prognosis in patients with IgA nephropathy was 17.24%,and the expression rates of P21 and PCNA positive cells in glomerular mesangial tissue of patients with poor prognosis were higher than those in good prognosis group(P<0.05),while the expression rate of P27 positive cells was lower than that in good prognosis group(P<0.05).Logistic multiple regression analysis showed that elevated diastolic blood pressure,increased 24 h proteinuria,mesangial cell proliferation,segmental glomerulosclerosis,renal tubular atrophy/interstitial fibrosis,crescentic body,increased expression rates of P21 and PCNA positive cells and decreased expression rate of P27 positive cells were all risk factors affecting the poor prognosis of patients with IgA nephropathy(P<0.05).Conclusion:There are positive expressions of P21,P27 and PCNA in glomerular mesangial tissue of IgA nephropathy.The expression rates of P21 and PCNA positive cells in glomerular mesangial tissue of of patients with poor prognosis of IgA nephropathy are higher than those with good prognosis,while the expression rate of P27 protein positive cells is lower than those with good prognosis,which are risk factors for poor prognosis of patients with IgA nephropathy.

BACKGROUND: Rheumatoid arthritis (RA), a chronic systemic autoimmune disease, is characterized by synovitis and progressive damage to the bone and cartilage of the joints, leading to disability and reduced quality of life. This study was a randomized clinical trial comparing the outcomes between withdrawal and dose reduction of tofacitinib in patients with RA who achieved sustained disease control. METHODS: The study was designed as a multicenter, open-label, randomized controlled trial. Eligible patients who were taking tofacitinib (5 mg twice daily) and had achieved sustained RA remission or low disease activity (disease activity score in 28 joints [DAS28] ≤3.2) for at least 3 months were enrolled at six centers in Shanghai, China. Patients were randomly assigned (1:1:1) to one of three treatment groups: continuation of tofacitinib (5 mg twice daily); reduction in tofacitinib dose (5 mg daily); and withdrawal of tofacitinib. Efficacy and safety were assessed up to 6 months. RESULTS: Overall, 122 eligible patients were enrolled, with 41 in the continuation group, 42 in the dose-reduction group, and 39 in the withdrawal group. After 6 months, the percentage of patients with a DAS28-erythrocyte sedimentation rate (ESR) of <3.2 was significantly lower in the withdrawal group than that in the reduction and continuation groups (20.5%, 64.3%, and 95.1%, respectively; P  < 0.0001 for both comparisons). The average flare-free time was 5.8 months for the continuation group, 4.7 months for the dose reduction group, and 2.4 months for the withdrawal group. CONCLUSION: Withdrawal of tofacitinib in patients with RA with stable disease control resulted in a rapid and significant loss of efficacy, while standard or reduced doses of tofacitinib maintained a favorable state.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

OBJECTIVE To optimize the extraction process of polysaccharides from Dendrobium officinale， and preliminarily study its effect on acute lung injury （ALI） in mice. METHODS Using D. officinale as raw material， the polysaccharides were extracted from D. officinale by ultrasonic-assisted hot water immersion. Using the extraction rate of D. officinale polysaccharides as response value， the single-factor experiments and Box-Behnken response surface method were used to optimize the ratio of material to liquid， extraction time and extraction temperature. ALI mice were induced by lipopolysaccharide. Using prednisone acetate （5 mg/kg） as the positive control， the effects on the mass ratio of wet and dry lung and pathological changes of lung tissue （HE staining and Masson staining） of low-dose， medium-dose and high-dose D. officinale polysaccharides （50，100，200 mg/kg） were investigated. RESULTS The optimal extraction technology of D. officinale polysaccharides was as follows： the ratio of material to liquid was 1∶25 （g/mL）， the extracting time was 1 h， and the extracting temperature was 58 ℃ . Under these conditions， the average extraction rate of D. officinale polysaccharides was 37.75% （RSD＝1.12%，n＝3）， the relative error of which with predicted value （38.63%） was 2.28%. Compared with the model group， the ratios of wet and dry lung in the positive control group and D. officinale polysaccharides groups were all decreased significantly （P＜0.05 or P＜0.01）， and the pathological changes in lung tissue （severe destruction of alveolar structure， significant widening of alveolar septa， extensive infiltration of inflammatory cells and proliferation of fibroblasts） were alleviated to varying degrees. CONCLUSIONS The optimal extraction process of D. officinale polysaccharides is feasible； the obtained polysaccharide extract has a certain improvement effect on ALI in mice.

Objective:To evaluate the value of growth differentiation factor 15(GDF-15)and hepatocyte growth factor(HGF)in mortality prediction for patients with chronic heart failure(CHF)during a 5-year follow-up.Methods:This prospective case-control study enrolled 141 CHF patients hospitalized at the First Affiliated Hospital of Anhui Medical University between August 2015 and September 2017, including 59 with preserved ejection fraction(HFpEF)and 82 with non-preserved ejection fraction(non-HFpEF). Using all-cause mortality as the endpoint during the 60-month follow-up, there were 93 cases in the survival group and 48 cases in the death group.Clinical baseline data of patients in the two groups were compared, and the prognostic value of GDF-15 and HGF for CHF was assessed using multivariate logistic regression analysis, receiver operating characteristic curves(ROC curves), the area under the ROC curve(AUC), and Kaplan-Meier survival curves.Results:The results of multivariate Logistic regression analysis showed that GDF-15, HGF, glomerular filtration rate, and body mass index were independent risk factors for CHF prognosis during the 60-month follow-up; The degrees of predictive ability on mortality in 60-months in patients with heart failure were estimated for GDF-15( AUC=0.769, 95% CI: 0.685-0.854), HGF( AUC=0.765, 95% CI: 0.676 to 0.854), body mass index( AUC=0.689, 95% CI: 0.594 to 0.783), and glomerular filtration rate( AUC=0.612, 95% CI: 0.518 to 0.705). The AUC values of GDF-15 and HGF were greater than those of the body mass index and the glomerular filtration rate.Using GDF-15=2 326 ng/L and HGF=1, 603 ng/L as the cut-off values, the Kaplan-Meier survival curves showed statistically significant differences in survival rates between the two groups( P<0.05)The mortality rate in the non-HFpEF group was higher when GDF15 ≥2, 326 ng/L and HGF ≥1, 603 ng/L(100%, 15/15)than that in the HFpEF group(50%, 2/4), and the difference was statistically significant( χ2=5.526, P<0.05). Conclusions:GDF-15, HGF, the estimated glomerular filtration rate and the body mass index are independent prognostic risk factors for CHF during a 60-month follow-up period.GDF-15 and HGF are independent predictors of all-cause death in patients with CHF, especially those with non-HFpEF during 5-years.
